Abstract

This study aimed to reveal correlation, calculate significance, and discover the regression equation of rice production to Green House Gas (GHG) emission in North Sulawesi Province. The data on GHG emissions from rice cultivation (Gg CO2eq) was obtained from the Ministry of Environment and Forestry of Indonesia. Data on rice production from wetland and dryland (Gg) was from the BP Statistical Review annual period of 2000-2021, both for North Sulawesi Province. Data analysis of correlation coefficient, F-test for Regression, and Simple Regression Analysis will be processed with the help application of MS Excel. The results show that the correlation between rice production and emission of rice cultivation in North Sulawesi Province is 0.53 and classified as a moderate correlation. The coefficient of determination stated that the emission of rice cultivation could be explained by about 28.6% from rice production. Therefore, rice production is statistically significant to the emission of rice cultivation with a 5% confidence level for North Sulawesi Province. Furthermore, this study found a regression equation, emission of rice cultivation is 112.67 + 0.516 times rice production. Keywords: correlation coefficient, green house gas emission, rice production

北苏拉威西省水稻生产与温室气体排放的相关性

本研究旨在揭示北苏拉威西省水稻产量与温室气体(GHG)排放的相关性，计算显著性，并发现回归方程。水稻种植的温室气体排放数据(Gg CO2eq)来自印度尼西亚环境和林业部。北苏拉威西省湿地和旱地水稻产量(Gg)数据来自《BP统计评论》2000-2021年年度数据。相关系数的数据分析，回归的f检验，简单回归分析将在MS Excel的帮助下进行。结果表明，北苏拉威西省水稻产量与水稻种植排放的相关系数为0.53，属于中度相关。测定系数表明，水稻种植的碳排放约有28.6%来自水稻生产。因此，在北苏拉威西省，水稻产量对水稻种植的排放量具有统计学意义，置信水平为5%。此外，本研究还建立了回归方程，即水稻种植排放量为水稻产量的112.67 + 0.516倍。关键词:相关系数，温室气体排放，水稻生产
